Specification of Letters Patent.

Application filed May 3. 1911. Seria1No. 624,840.

To all whom it may concern:

Be it known that I, ROBERT F. Bowen, a citizen of the United States of America, residing at Detroit, in the county of Wayne have invented certain new and useful Improvements in Roller- Bearings, of which the following is a speci fication, reference being had therein to the accompanying drawings.

The invention relates to roller bearings of that type in which the rolls are subjected to both radial and end-thrust, and the invention consists in the means employed for spacing and retaining the rolls, and further in features of the construction as hereinafter set forth.

In the drawings,Figure 1 is a perspec-, tive view of the bearing; Fig. 2 is a cross section therethrough; Fig; 3 is an end elevation; Fig. 4 is a plan of the blank from which the spacer is forme j A is the annular bearing or recess around which the rolls travel and which is provided with a groove B.

C are the rolls surrounding the bearing A each being provided'with a flange D for engaging the groove B, the faces of said flange and groove being preferably beveled.

For suitably spacing the rolls and retaining the same. in relative position, a spacer member E is employed. This as shown in V'Fig. 4 may be formed from a fiat blank of sheet metal having a ring portion G and outwardly extending lugs I-I connected to the ring by necks I of lesser width. In assembling the bearing the rolls are placed about the member A with their flanges D in engagement with the groove B. The member E is then placed with the ring Gr surrounding the member A after which the lugs H are bent at the point of juncture between the necks I and ring, into a position extending at substantially right angles to the plane of the rin their opposite edges will contact with the outer faces of the rolls, while the shoulders J bearing against the flanges D will prevent endwise disengagement of the lugs from the rolls and hold the axes thereof parallel to the axis of the hearing. The lugs H are also Gopiet of this patent may be obtained for five cents each, by addressing the Commissioner Watch, In, it

G. When the lugs are thus bent;

preferably bent at their opposite edgeg as indicated at K so as to form a bearing surface-tangent to the roll.

In operation the retainer F constructed as described, will hold the rolls properly spaced and in alinement in engagement with the bearing member A and permit of engaging the assembly with the cooperating annular hearing by an. endwise movement.

What I claim as my invention is:

1. In a roller bearing, the combination with a race member having an annular parallel portion and an' adjacent annular groove, of rolls spaced about said member each having a parallel portion engaging the parallel portion of said race member and an enlargement engaging said groove, and a retainer comprising a ring adjacent to the ends of said rolls, having a bearing face therefor and bent lugs extending between said rolls of greater width than the minimum space between adjacent rolls and provided with cut away or contracted necks providing clearance for said enlargements, and shoulders opposed to the bearing'tja'c of said ring engaging the inner factsgof said enlargements and holding the same against said ring.

2. In a roller bearing, an annular racemember having an annular groove therein,

a series of rolls arranged around said race member each having an enlarged head engaging said annular groove, and a retainer comprising a ringbearing against the ends of the rolls, and bent lugs extending between said rolls of greater width than the minimum space therebetween to space and retain said rolls upon said race n1ember, said lugs having cut awa or contracted necks provliding clearance or said enlargements, and shoulders engaging the inner faces of said enlargements to hold the rolls against said ring.

In testimony whereof I ailix my signature in presencebftwo witnesses.
